ive got a 99 sierra 5.3, pacesetter lts with 3 inch true duals & single chamber flows, ported tb, k&n gen 2, TB converter, ud pullies, and electric fans. im either about to order some 1.8 rockers or a nelson tune. im going to end up doing both things but which one should i do first? are the rockers worth doing?

 

Stocker Rockers, dont waste your money on 1.8 rockers you will not benefit from them. Do you even have a cam? Now the Nelson Tune is a given, that should have been your second mod right after the Pacesetters. Rockers are like throttlebody spacers!

 

I'll second the tune it should have been one of the first mods

take the money for the rockers and get cam and springs or gears and LSD

 

Leave your stock rockers. They are a good rocker arm for blown applications, Cams, and NO2.
Definately go with the Nelson Tune! You'll love it!

Tune!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

Whats up with everone wanting to put rockers on their trucks lately???

Dude, get a tune.

 

I really wish I knew.

 

Definitely a tune!

 

Tune FTW

 

Go with the Tune and don't waste money on Ratio Rockers. They are not worth the money. Later on go with a Cam and Stall Setup but don't waste any money on 1.8 rockers
